1. For the
Raymond mill Powder Machine normal, should develop equipment "equipment maintenance safe operation of the system" can ensure the long-term safe operation of Raymond mill, also have the necessary repair tools and grease and the corresponding accessories.
2. Raymond mill roller mill plant using more than 500 hours or so to replace the roller when the roller bearing kit must be cleaned of all, the damaged parts should be replaced, fuel pumps and hand tools available grease gun .
3. Raymond mill in the use of the process, care staff should be fixed, the operator must have a certain level of technology. Raymond mill operators in the installation must be carried out before the necessary technical training to enable understanding of the principles of performance of Raymond mill, familiar with operating procedures.
4. Raymond mill used for a period of time, maintenance should be carried out. Meanwhile, roller blade grinding ring overhaul replacement of wearing parts such as processing, grinding roller device before and after the connection using bolts and nuts should be carefully examined to see if There loosening, whether to add a little grease.
Raymond mill repair and maintenance
It consists of the host, the fineness of machine, blower, finished cyclone powder collector, bag filter and connecting air tube. According to user needs can be equipped with crusher, elevator, storage bin, electromagnetic vibrating feeder and electrical control cabinet and other auxiliary equipment. In the host, through the cross arm roller shaft assembly hanging in the hanger roller, roller blade knife hanger with the spindle and the fixed link, the pressure spring chamber pressure in the roller bearing surface of the outer end of the cantilever to cross arm axis as a fulcrum to force the roller pressure in the grinding ring tightly round the surface, when the motor drive shaft through the rotation transmission device, installed on the shovel blade knife with synchronous rotation roller, roller circle in the ring rolling mill rotation around its own axis at the same time. Driven through the transmission of the motor impeller rotation, the higher impeller speed, sub-sub-elected finer powder.
Raymond mill work process: Bulk materials are crushed by the elevator sent to the storage hopper, then a continuous feeder into the grinding room evenly into the grinding chamber of the material is shovel blade and into the ground between roller and grinding ring crushed grated, fans will be blown into the air from the surrounding base grinding chamber, the material will be crushed into the analyzer, the large particles fall back to re-grinding the material, with the air passing into the finished product is powder cyclone powder collector, powder and separated from the discharge port of air discharge is finished. Return to top of fans in the air and repeat the cycle.
In the mill was grinding the material in the interior due to a certain moisture content, grinding and heat production caused when water evaporates, and the whole of the pipe connection to the outside world does not close the gas is inhaled, so that increased air circulation flow, to ensure the mill in the negative work under pressure, the increase in air flow between the host through the fan into the bag filter over the trachea, was purified into the atmosphere.
Raymond mill operation:
Raymond mill start, should check whether all the access door closed tight, jaw crusher plate check whether the feed size gap size, adjust the machine speed should be of similar analysis of product size requirements. Finally, according to the order of the boot.
1. the starting bucket elevator;
2. starting jaw crusher;
3. there are materials to be silos, the starting of machines;
4. start the blower (air load start running until after the load);
5. Start
Raymond mill hosts, start host instant starts electromagnetic vibrating feeder. At this point the work of Raymond mill is the beginning.
Raymond mill simple sequence of operations is as follows: Start: elevator crusher fans of the host machine feeder. Raymond mill shutdown of the machine should be shut down following order:
1. turn off the feeder stopped feeding;
2. about a minute to stop the host;
3. the blowing of the powder will stop after residue blower;
4. the final closure of machine.
Raymond mill shutdown sequence is: the host feeder Blower analysis machine. Note: The transport of materials to enhance the machine after a certain amount of silo, the first stop after stop crushing machine and upgrade the current changes in the feeding amount by the reservoir.
Raymond mill freely in normal operation are not allowed to cheer, to ensure production safety, milling machine in any part of the unusual noise, or sudden increase in load should immediately stop inspection, troubleshooting, in order to avoid a major accident. Then continue to boot more than expected the
raymond mill must be removed, otherwise the boot when the current is too large, of the startup.
